To aZZ whom it may concern:

Be it known that I, JAMES N. WRIGHT, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Presses, of which the following is a specification, reference being had therein to the accompanying drawings, in

Figure l is an elevation of my improved press, parts of which are broken away for the purpose of exposing to view certain other parts behind them. Fig. 2 is an elevation of one side of the machine. Figs. 3, 4, 5 are details of parts of the machine, which I will hereinafter describe. Fig. 6 is a section in detail, showing connection of shaft 0 with shaft 0, and also the ejecting devices.

My invention relates to improvements on presses which are especially applicable to the press for which Letters Patent were granted J. H. Brinkop on the 31st day of May, 1881, numbered 242,258; but the devices which I shall describe may be applied to other presses without changing the nature of myinvention, which consists, esse ntially,in the devices'which I shall point out and claim, and which will be fully understood from the following description, when taken in connection with the annexed drawings.

My object is to press tobacco (or other material) into plugs or lumps, and to secure a uniformity of the pressed material; and also to construct a mold with an adjustable back plate, a stationary bottom, movable ends, and a hinged apron forming the front of the pressbox, in combination with a vertically-movable plugger.

A designates the rigid frame of the machine, which is constructed with journal-bearings for a main driving-shaft, B, on one end of which I key a belt-drum, B, for the purpose of driving the machine by steam or other convenient power, in lieu of using foot-power, although a treadle may be used, if desired. Inside of this press-frame, and rigidly secured to it, is an angular bracing-frame, B which is so constructed that it affords a substantial bed for the platen or table V. This table is horizontal and innnovably fixed to the main pressframe A, and it is cast with vertical guides c,

for the purpose ofholding the dovetail draws d.

' These devices will sustain the horizontal and head or bridge, F, which I prefer to construct of cast-steel. To this bridge F the plunger F is rigidly secured, which plunger is vertically movable in the press-box l E E designate loops or connecting-pieces,

which are femalescrew-threaded and applied on the trunnions t t of the said cross-head or bridge F, that play vertically in slots made through the uprights of the main frame A. Into said loops E is screwed pitman-rods E, which are provided with jam-nuts E at their upper ends. The lower ends of the pitmanrods E are similarly connected to T-shaped couplings E, which are applied to wristpins w, on the free ends of cranks m, that are keyed on the ends of a horizontal oscillating shaft, 1), which has its bearings in the angular bracing-frame B. I

It is obvious that by loosening the jam-nuts on the pitman -rods E, they can be turned, and that the strokes'of a plunger, hereinafter explained, can be lengthened or shortened, or the wear and tear of the parts compensated for.

Between the limbs of the intermediate or bracing frame, B a crank, it, is applied on the shaft 1), and connected to the crank P by a rod, 1*. The crank I? is fast on one end of the short shaft 0, and supported in bearings formed in the brace n. This shaft 0 extends out through one of the cheeks of the press-frame, and has keyed on it a large spur-wheel, q. The shaft 1) oscillates about one-quarter of a revolution, which movement brings the follower down, thus producing the pressure upon the material in the press-box, the power and motion being thrown off quasi-automatically by a catch, V, on the outer face of the gear q, impinging with a catch, a, on adjusting hand-lever t, which at the same time forces the clutch K out of gear and retains pressure on the work. The clutch K is then thrown into gear by the starting-lever, which revolves shaft 0, giving to shaft b one-quarter of a revolution, which movements raise the plunger. As the crank on shaft 0 revolves, it strikes the long arm-of a lever, 2, and raises an ejector, 3, and discharges the p resscd plug of tobacco from the press-box.

The large gear-wheel q is driven by the clutchpinion J, which turns loosely on the shaft B,

and, by means of a feather on the clutch and a groove in said shaft, the coupling or shifting of the parts is effected,the shaftB being constantly moving. The arm to, supported by the angular brace n, is for the purpose of lifting the compressed mass or lump after the completion of the pressing operation, which arm is actu-' ated by the crank P, pushing it outward. The arm to will, by its own gravity, drop into its place after the said crank releases it.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a pressing-machine, the combination of the main frame, the auxiliary angular bracing-frame, and the table of the press, all construeted and adapted to operate substantially in the manner and for the purposes described.

2. The combination, in a press, of the brace B adapted to support the table V at the middle thereof, the guides c c, rigid 011 the table the adjustable draws d, for holding and adjusting the back plate of the mold, and the cross-head or bridge, all constructed and adapted to operate substantially in the manner and for the purposes described.

3. In a press of the character described, the combination of the vertically-movable crosshead guided in the main frame, with the loops,

the adjustable pitman-rods, and the crank on the shaft b, substantially as and for the purposes described.

4. In a press, the combination of the shaft 1), the angular bearing-brace therefor, the t-hrc e cranks thereon, the shaft located at the back of the press-frame, and provided with a pulley, the clutch K, the device r, the crank P, the brace fastened to the angular brace, the shaft 0, and the gear q, having an automatic throw-off catch, and the catch a, attached to the starting-lever,-all constructed and adapted to operate substantially in the manner and for the purposes described.

5. The combination, in a press, of the starting-lever, the catches 'v a, the spur-wheel g, and the clutch and its pinion on the belt-drum shaft B, substantially as described.

6. The combination, in a press of the charaeter described, of a main supporting-frame, an intermediate angular frame, a press-table supported thereon, and a vertically'movable eross-head guided thereby, all constructed and adapted to operate substantially in the manner and for the purposes specified.

In testimony whereof I aflix my signature in presence of two witnesses.
